Broke a value Spring
One of my EX Components valve spring broke the other day. Sounded like the whole engine had blown up. Thought for sure we had spun a bearing, but when we took the valve cover off, there it was.
The valve tapped the piston put about a .019 nick in it on the exhaust side. Everything else looks good. No metal flakes in the oil, spark plugs look great.
Is there any reason I should be leering of the engine now? I would think everything is ok, but wanted to see if anyone knew of something I should be concerned about.
Here are some pictures. BTW that is a reflection on the wall above the piston in that picture.

I broke a Crane Dual spring about 1month ago.

That is what happened to the dual spring one of the cylinders.
I got lucky and it didnt bend the valve. I assume you bent the valve and going to replace it. I would think the piston is fine if you really dont want to replace it.

I assume my valve is bent, we are going to redo the heads with all new valves and springs. We turned the crank and the piston moves normally, so I believe all is well on the bottom side. Guess we both got lucky!

I would just compress the cylinder with compressed air, if the valve spring is completely shattered and you can move the valve up and down by hand, I would check to see if its straight by spinning it and seeing if the shaft moves around or spins on center. If so, you are fine, as I was.
Then as the air is in the cylidner, see if the valve seals, if it seals and you cant push it back down by hand, then its definetely good, as I was.
I just got lucky that even both broke it didnt hit the piston, but I will know in a few days since Im removing the head to put in my new AFRs I think I was lucky cause the springs were still holding the valve up even though it was shattered in those pieces, I still had to compress it to remove the retainers.
